If you match the amount of static friction that can be generated when the object is at rest, it will not move because there is zero force the force has to be greater that the static friction in order to have it include motion. But if there was any more force will cause acceleration otherwise if it was lower force it will deceleration.
Answer:
1.85c
Explanation:
a photon moves at c, the electron is moving at 0.85c, and since they are moving in opposing directions, the relative speed would be 1.85c

Answer:
V₂=153.84 m L
Explanation:
Given that
Initial volume ,V₁ = 200 m L
Initial pressure ,P₁= 500 torr
Final pressure P₂ = 650 torr
Lets take the final volume =V₂
Given that process occurs at constant temperature and we know that for constant temperature process
P₁ V₁ = P₂ V₂
![V_2=\dfrac{P_1V_1}{P_2}](https://tex.z-dn.net/?f=V_2%3D%5Cdfrac%7BP_1V_1%7D%7BP_2%7D)
Now by putting the values
![V_2=\dfrac{500\times 200}{650}\ mL](https://tex.z-dn.net/?f=V_2%3D%5Cdfrac%7B500%5Ctimes%20200%7D%7B650%7D%5C%20mL)
V₂=153.84 m L
Therefore the new volume of the gas will be 153.8 4mL.
Any vector which is made in x-y plane will have some angle with the x axis
in that case we can say that
![P_X = P cos\theta](https://tex.z-dn.net/?f=P_X%20%3D%20P%20cos%5Ctheta)
also for Y direction we can say
![P_y = P sin\theta](https://tex.z-dn.net/?f=P_y%20%3D%20P%20sin%5Ctheta)
so here the two components of vector is given by Px and Py
so we can say that
![\vec P = (Pcos\theta)\hat i + (Psin\theta)\hat j](https://tex.z-dn.net/?f=%5Cvec%20P%20%3D%20%28Pcos%5Ctheta%29%5Chat%20i%20%2B%20%28Psin%5Ctheta%29%5Chat%20j)
so correct answer would be
<em>Vectors Px and Py are components of vector P.</em>
